Fuel supplement

Adding methyl -butyl ether (MTBE) to the gasoline pool. Of all the (cost-effective) organic fuel supplements tested, MTBE had the highest octane number.

Impurities in the drying atmosphere are exhausted in the air and have been referred to as "blue haze." One company has made substantial progress in collecting the blue haze emissions in a duct where they are directed through a series of water showers, filters and other equipment. Then the water is evaporated leaving a heavy liquefied residue which is collected on a stainless steel belt and deposited in storage vats. Currently this residue is being used as a fuel supplement, but some feel that it may be a future source for development of new chemicals. Apparently, this process meets Environmental Quality Standards with reference to air pollution. 

H2 can also be used to capture carbon monoxide and COz in the combustion products. C02 can be converted into methanol. Each mol of C02 will require 3 mol of H2 to generate 1 mol of methanol (CH3OH). After recovering this methanol, it can be used as a fuel or fuel supplement, thereby reducing the need for burning coal, natural gas, or other fossil fuels, whereas the emission of C02 will also be reduced. 

Will Methanol Replace Gasoline Perhaps the most promising future use of methanol is as an automotive fuel supplement. There are four ways in which this can be achieved. 

New Zealand also has no significant oil reserves but large natural gas and coal deposits. The New Zealand government has committed the country to the use of methanol as a fuel supplement. This methanol will be manufactured from natural gas reserves and perhaps, in the long term, from coal. 

Of the three basic methods of disposal of used lubricants, the most efficient in terms of energy conservation, in that it displaces an equivalent amount of oil, is the use of the material as a fuel or a fuel supplement. In heating processes where the fuel is supplied through a burner, some limited pre-treatment of the waste lubricants and blending with conventional fuels is necessary. 

Definition of Pyrolysis. The word pyrolysis has had some problems in definition, especially when applied to biomass. The older literature generally equates pyrolysis to carbonization, in which the principal product is a solid char. Today, the term pyrolysis is generally used to describe processes in which liquid oils are preferred products. This symposium was concerned with the latter pyrolysis - processes which offer enhanced yields of liquid oils, especially those with desirable chemical compositions and physical attributes for liquid fuels, fuel supplements and chemical feedstocks. 

Solid waste such as tires has been use in cement kilns as fuel supplement for making Portland cement. In an Atlanta, Georgia, plant, the use of tires has decrease the plant s air emissions by up to 30% and allows the company to meet tighter nitrogen oxides (NO c) guidelines [94], The use of carpet waste in cement kilns is also quite attractive and an effort is being made in this direction [95]. The relatively high fuel value of carpet polymers can reduce the need for fuels, and the calcium carbonate in carpet becomes raw material for cement.

Tire-derived fuel used as a fuel supplement comes in three main forms. In some cases, whole tires have been injected into a boiler and burned. Others require that tire crumb be produced without any steel and less than about 6 mm size. The most common size for utilizing TDF is between 25 nun and 50 nun squares with the steel removed. The economics of chipping to finer sizes and removing the steel are very important in determining the long-term potential for TDF usage. This section provides typical analyses of the TDF, including those analyses required for fuel specification in combustion systems.
